Reformation and Application of Sensor Experimental Platform Based on ZigBee

针对传感器实验设备功能单一、移动性差等问题,分析江汉大学传感器与检测技术实验平台的结构特点,设计了一种基于ZigBee技术的传感器实验平台。该实验平台是在现有传感器实验平台上进行改进,通过增加ZigBee无线通信功能,使其同时满足传感器技术和无线传感器网络两门课程实验教学的需求。该系统由传感器实验模板、ZigBee终端节点、ZigBee汇聚节点和PC机组成,各终端节点连接不同的传感器模板,将采集的数据通过ZigBee无线网络传送给汇聚节点,并最终传送给PC机观测。在介绍该实验平台的软硬件设计之后,以基于ZigBee的无线应变传感器实验为例,详细介绍了如何利用该平台开展实验项目。结果证明,该实验平台数据传输可靠,满足实验教学需求。

In order to solve the problems of single function and poor mobility of the sensor experimental equipment,the sensor experimental platform based on the ZigBee technology was presented after analyzing the structural characteristics of sensor and detection technology experimental platform in the writer′s school. Based on the ZigBee wireless communication function,the existing sensor experiment platform was reformed to meet the needs of the experimental courses of sensor technology and wireless sensor network. The system consisted of sensor experimental templates,ZigBee terminal nodes,ZigBee sink node and PC. Each terminal node was connected with different sensor templates,the collected data was transmitted to the sink node through the ZigBee wireless network,and finally transmitted to the PC. After introducing the hardware and the software design of the experimental platform,taking the wireless strain sensor experiment based on ZigBee as an example,this paper introduced how to use the platform to carry out the experiments. The results showed that the experimental platform was reliable in data transmission and met the needs of experimental teaching.
